As you know, "Number Place" is the famous puzzle in a world. It is known as "Sudoku *1". Therefore, we do not explain about the rules. If you do not know about it, please search the word on web.


"Hyper Sudoku" has one more rule than Standard Sudoku that has 9 grids by 3x3. Hyper Sudoku has 4 more 3x3 blocks than standard Sudoku. Please see screenshots, you will see four blue-colored 3x3 blocks in puzzle board. You must fill all empty cells so that the numbers 1 to 9 appear exactly once in each row, column and 3x3 blocks.


In addition, I have also included "SDK Hyper Diagonal". Rules of "SDK Hyper" apply. Additionally, no digit repeats on diagonals.


In this application, we adopted a new input method "Thumb One" for a smart phone. When you are working with a smart phone with one hand, you can enter the answer and pencil marks in just thumb of one hand.

If you are interested in "Thumb One", please see this movie.
